About:
PhysUnits is a header-only C++ library for compile-time dimensional analysis and unit conversion. It enables type-safe manipulation of physical quantities, ensuring unit consistency and preventing errors in scientific calculations. The library leverages C++11 features for zero-overhead abstractions, making it suitable for performance-critical applications.

Key Features:

Header-only library requiring no build or installation
Compile-time unit checking and conversion for type safety
Supports SI units and derived units (e.g., Newton, Joule, Watt)
Zero runtime overhead with optimized template metaprogramming

Use Cases:

Physics simulations and scientific computing
Engineering applications requiring unit safety
Embedded systems with strict performance constraints

Alternatives:

units – Units library by NVIDIA; similar compile-time safety but with different API design and C++20 focus
boost.units – Part of Boost; more feature-rich but heavier dependency and longer compile times
